Our approach to office management of asthma exacerbations in adults and adolescents

PEF: peak expiratory flow; SpO₂: pulse oxygen saturation; SABA: short-acting beta-agonist; MDI: metered dose inhaler; GC: glucocorticoid; LABA: long-acting beta-agonist.
* In a minority of patients, symptoms resolve quickly and completely with one dose of albuterol (eg, 2 to 4 inhalations or one nebulizer treatment) and PEF is ≥80% of predicted or personal best. Oral glucocorticoid is not necessary, but a step-up in controller medication may be needed.

Δ Comorbid conditions that may complicate asthma exacerbation include the following:

• Acute bronchitis
• Acute bacterial sinusitis
• Heart failure; arrhythmia
• Influenza, COVID-19
• Pneumonia
• Pneumothorax

Suggestive symptoms include fever, myalgias, purulent sputum, chest pain, poor response to SABA. Refer to UpToDate content on diagnosis and management.
◊ Individuals with PEF 60-70% of predicted following initial treatment can sometimes safely continue treatment at home if their symptoms are improving, they have an asthma-safe home environment, have the necessary medications and understand their proper administration, are deemed adherent to therapy, and have ready access to emergent care if needed.
